Family members say Doug Boucher was mentally ill when he started to yell at a store clerk in December 2009. When Mason police arrived and tried to arrest him, Boucher was shocked with a Taser and fell to the ground, causing a skull fracture that led to his death, the suit states.

The officers claimed that Boucher struck one of them in the head while they struggled to handcuff him.

The family says the two Mason officers tortured Boucher by striking him with batons after he was on the ground and shocking him five more times with the Taser.

The city is also accused of failing to follow policies for the use and testing of Tasers.
